Application filed December 23,1926.

The present invention is directed to imand arranged in such manner that it can be easily placed for operation without the necessity of driving the car upon a rack or over a pit, or necessitating a person crawling under the car to drain the case, as is now customary,

Another object of the invention is to provide a device of this kind so constructed that it can be operated to remove the drain plug, the construction being such that after the case has been drained, the plug can be replaced. e V e In the accompanying drawing:

Figure 1 is a side elevation of the device, showing the same under a crank case, and in position for re 'ioving the plug therefrom.

Figure 2 is a similar view showing the device in posit-ion after removing the 1 plug for draining the case.

Figure 3 is a sectional view on line 33 of Figure 1. r

Figure 4 is a sectional view on line 4-4 of Figure 1.

Figure 5 is a top plan view of the device.

The device comprises a pan 1 preferably oval in shape and having a pair 'of posts 2 secured to the bottom thereof, and ad acent one end, said post pivotally supporting the rock shaft 3, the purpose of which will later appear.

The tubular handle 4 is provided and in this handle is rotatablymounted a driving shaft 5. The handle is suitably secured ad- 'acent its inner end to the rock shaft 3 in changed. The handle not only performs its function, but serves as a housing for the shaft 5. To facilitate the operation of the device, the handle 1 is provided with hand grips 6. Havingtheir lower ends fixed to the handle 4: are bars 7 and supported by the upper'ends of said bars is a tubular housing 8 in which is rotatably mounted a shaft 9, the upper end of which is provided with a "thoroughly drained,

squared head 10, the lower end of said shaft having fixed thereto a beveled gear 11 which meshes with a similar gear 12 fixedto the inner endof the shaft 5. The shaft 5 has its outer end provided with a squared head 13 and engaged therewith is a crank shaft 14-, through the medium of which the shaft 5 is rotated to transmit rotary movement to the shaft 9.

A socket member 16 isengaged upon the head 10, it being essential of course that the same beof a sizeto conveniently engage the 1 plug, 17 of the crank case 18, and in order to do this we have prov de socket members of various sizes.

In operation the pan 1 is placed underthe deemed'it desirable to crank case 18 and through themedium of the handle 4. A selected socket member is engaged with the head 10'and with the drain plug 17 and upon imparting rotary movement to the shaft 9 through the shaft 5, the plug will be unscrewedand retained in the socket member, whereupon the handle is swung upwardly in order to move the plug from under the drain opening, thus permitting free flow of oil from theopening into the pan 1, After the crank case has been the handle is rocked downwardly, thus bringing the plug 17 to a position to be screwed into the drain opening upon reversely rotating the shaft 9 through the medium of the shaft v5.

It will be observed that the shaft 9 is disposed in acute angular relationship withrespect to the handle 4 and that'when the shaftb is being move or replace the plug 17 it will assume a true perpendicular position.

Having thus described the invention, we claim:

1. In a drain plugs of'crank cases for the purpose specified, comprising in combination, a pan, a tubular handle pivotally-supported on the pan, a driving shaft rotatable in the handle, a housing supported by the handle, a driven shaft rotatable in the housing, a gear connection between the driving and driven shaft, a socket member detachably engaged with the. driven shaft for engagement with the drain plug upon pivotal movement of the shafts and rotatable with the driven shaft, as and for the purpose'set forth.
